What? Just because predicting human behaviour one minute before it's happening with 99% accuracy is more impressive, it doesn't mean that it involves any kind of different process than predicting human behaviour 5 seconds before with 60% accurateness. Admittedly, it might imply different kind, maybe even unachievable or uncomputable kind of process, but it also may be just a matter of better probes/more computational power.

So would you have been wiling to draw the same conclusion from an experiment that predicted the button pushing 1 second before with 99.99999% probability by scanning the neurons in the arm?
